I get that when data is going to be accessed in sequence, a clustered index will keep it all physically ordered on a disk and that caching of the data by the disk controller will likely result in your next needed record being in memory already (although I have questions about how true that is if multiple people are accessing the database at the same time, causing the disk to spin).

Morphology
The meaning is directly and transparently derived from combining 'disk' (the storage device) with 'controller' (an instrument that controls or regulates): it denotes a device that controls a disk. This noun+noun instrument composition is a common, predictable pattern (even across languages) so a B1 learner who knows the parts can infer the MWE's meaning despite its technical context.
Etymology
Disk controller: The name disk controller comes from the picture of a small controller telling a round disk what to do. In a computer, this part 'translates' the system's orders into messages the disk can use to read or write data, so the name means the part that tells and controls the disk.
